Gws 101040 Square End Mill 3/16 in 3 Flute Carbide Zrn

Product Description

The GWS 101040 is a solid carbide square end mill designed for high-performance milling of aluminum and non-ferrous materials. Part of the Series 1025 Alumigator line, it features a 3/16-inch cutting diameter, a 5/16-inch length of cut, and three flutes with a 37-degree helix angle. The ZrN (zirconium nitride) coating reduces built-up edge and extends tool life in aluminum applications. The submicron carbide grade provides the hardness and wear resistance needed for precision cutting operations. This end mill is a single-end, right-hand cut, right-hand flute tool with an upcut flute type, suited for CNC machining centers and manual mills in professional shop environments.

The GWS 101040 is used in machining operations targeting aluminum, soft metals, and other non-ferrous materials where chip evacuation and surface finish are priorities. The three-flute geometry and 37-degree helix support aggressive feed rates while maintaining clean wall finishes. With a 3/16-inch shank diameter matching the cutting diameter and a 2-inch overall length, this tool fits standard collets and end mill holders commonly found in production and job-shop environments. It is center-cutting, allowing plunge entry when required by the operation.

Key Features

• 3/16-inch cutting diameter with matching 3/16-inch shank diameter for direct collet fitment
• 5/16-inch length of cut suited for shallow-to-medium depth passes
• Three-flute design with 37-degree helix angle optimized for aluminum chip evacuation
• ZrN coating reduces built-up edge and extends tool life in non-ferrous applications
• Submicron solid carbide grade for consistent edge sharpness and wear resistance
• Center-cutting geometry allows direct plunge entry

Compatibility

Designed as an OEM-style replacement and production end mill for standard 3/16-inch collets and end mill holders used in CNC and manual milling applications targeting aluminum and non-ferrous materials.

Installation Notes

Installation of end mills should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth per the holder manufacturer's specifications. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates edge wear and degrades surface finish.
